MEDIUM

Why flagged The PKGBUILD downloads a prebuilt AppImage binary from cdn.wostatic.cn, which appears to be wolai's own CDN (wostatic.cn is the static asset domain for wolai.com, a Chinese productivity/notes app). This is plausibly the official distribution host rather than a random third-party. However, it is not the primary domain (wolai.com), there is no GPG signature verification, and the binary is executed during build (--appimage-extract). The sha256sums provide some integrity protection, but if the CDN host is not under the project's control or is compromised, a malicious binary could be delivered. This is a standard AppImage packaging pattern for AUR, but the unofficial-looking CDN domain and lack of signature verification keep this at medium rather than clean.

Triggered rules

MEDIUM source=() URL on a non-standard host source_untrusted_domain

One or more source=() URLs point to a host outside the trusted allowlist (github.com, gitlab.com, codeberg.org, pypi.org, …).
